object plumbing commands

[cryptix]

updates #138

[whyrusleeping]

I wonder if there are any other encodings we would want to support...

[jbenet]

Depends on how nice we want to be. msgpack, xml, rdf, and so on do see some use.

[whyrusleeping]

Yeah, xml encoding might be nice to integrate with older systems

@cryptix awesome! thanks! a few comments up there, and one important note:

this doesn't work with a daemon, right? it's reading from os.Stdin, which is right on the client, but the code there will be executed in the daemon side, no?

Probably fine for now until we figure out what the commands library makes it look like. We'll need a way to pass io.Readers as arguments. cc @mappum

[cryptix]

Jep, that's right. Same issue as with the block commands. Waiting for @mappum's cmd stuff

[cryptix]

@jbenet i just noticed that I didn't yet add the commands to the daemon. So it won't work anyhow in this state.

[jbenet]

@cryptix ok that's fine let's just merge it anyway and transition it to daemon later.

[jbenet]

@cryptix (aside from the wording stuff, which I'll fix post merge) there's a few comments up there to address? Like:

• Break on max size object plumbing commands #185 (comment)
• No links isnt error object plumbing commands #185 (comment)
• Codec Interface object plumbing commands #185 (comment)

(At least the top two, i can handle the Codec interface if not of interest)

[cryptix]

Addressed the first two, not too sure where to place the codec interface and I think it's fine until we introduce more formats.
